Abstract

The invention discloses a management unit and method for realizing multi-task scheduling in a reconfigurable system, including a task generating module, a task parsing module and a task sending interface module; the task generating module is used to generate a reconfigurable array task, including the configuration information for configuring the reconfigurable array function, the configuration information for configuring the data flow, the corresponding target reconfigurable array number and the task number; the task parsing module: used for caching and parsing the target Reconfigurable array number and task number; the task sending interface module: used to send the task to the corresponding reconfigurable array, when the target reconfigurable array of the task is found to be the same in the task parsing module, send the task to multiple reconfigurable arrays at the same time A reconfigurable array. The invention improves the dynamic reconfiguration efficiency of complex reconfigurable systems.

Description

technical field [0001] The invention relates to the field of embedded reconfigurable design, in particular to a management unit and a method for realizing multi-task scheduling in a reconfigurable system. Background technique [0002] With the emergence of reconfigurable technology, the traditional embedded design method has been changed. Reconfigurable computing has broad application prospects in the field of embedded and high-performance computing. Reconfigurable computing architecture has been widely used in embedded systems in recent years. The design aspect has gained more and more attention, and its main application fields include multimedia processing, mobile communication, digital signal processing, data encryption and decryption, etc. The reconfigurable configuration control unit maps each subtask included in the algorithm application to each computing unit in the reconfigurable hardware by updating the configuration information on the reconfigurable hardware.
